Abstract

An arrangement for use in a utility meter (10) includes a sensor (18) and a processing circuit (14) supported by a base of the meter (10), and a magnetic element (24) carried by the cover (22) of the meter, in which the cover (22) is removably mounted to the base. The sensor (18) includes at least two magnetizable elements (102,103), such as inductors, that are magnetized at opposite polarities when the meter (10) is closed and operable. The magnetizable elements (102,103) are positioned in very close proximity so that as cover (22) is removed the magnetic element (24) passes the elements (102,103) to cause the magnetizable elements (102,103) to assume the same polarity. The processing circuit (14) continuously polls the magnetizable elements (102,103) to evaluate their respective polarities and is configured to issue a tamper indication when the detected polarities are the same.
